Description
Technical field
The present invention relates to a kind of microwave front end fallback circuit, particularly a kind of spaceborne ferrite microwave front end fallback circuit.
Background technology
Spaceborne ferrite microwave front end is as a kind of high-speed electronic switch, between transmitter, receiver and the antenna of satellite-borne microwave remote sensor, realize the microwave measurement signal from the transmitter to the antenna, antenna is to the switching of receiver, in the satellite-borne microwave remote sensor, bringing into play extremely important effect, its reliability is also being proposed higher requirement.
The spaceborne ferrite microwave front end of tradition all adopts the identical Realization of Product Redundancy Design of active and standby two covers, to improve the reliability of product.The microwave front-end circuit partly comprised in the past: driver A, magnet exciting coil A, ferrite switch A, driver B, magnet exciting coil B, ferrite switch B.Driver A directly links to each other with magnet exciting coil A, and magnet exciting coil A passes the magnetic core of ferrite switch A, and driver A encourages ferrite switch A by magnet exciting coil A; Driver B directly links to each other with magnet exciting coil B, and magnet exciting coil B passes the magnetic core of ferrite switch B, and driver B encourages ferrite switch B by magnet exciting coil B.
Adopt a whole set of microwave headend equipment numerous owing to microwave front end microwave interface as the mode of backup, so that microwave remote sensor complicated, needing increases such as the lower electrical category product of the reliabilities such as mechanical switch, the microwave remote sensor reliability is reduced, also can increase simultaneously the volume and weight of remote sensor payload, this is disadvantageous in spaceborne product.
Summary of the invention
The object of the present invention is to provide a kind of spaceborne ferrite microwave front end fallback circuit, solve that traditional fallback circuit brings because the system complex that the equipment increase causes, reliability reduce, volume becomes problem large and that weight increases.
A kind of spaceborne ferrite microwave front end fallback circuit, comprising: driver A, driver B also comprise: main magnet exciting coil, secondary magnet exciting coil, ferrite switch, wherein ferrite switch comprises: FERRITE CORE and cavity.
The cavity of ferrite switch is the cuboid metalwork, and inside is " Y " shape cavity, and FERRITE CORE is " Y " shape, places " Y " shape cavity center, and and cavity between gluing fixing.On three support arms of FERRITE CORE through hole is arranged all, a side of cavity has two through holes, the parallel through hole that passes on three support arms of FERRITE CORE of main magnet exciting coil and secondary magnet exciting coil, and the coil two ends pass from two through holes of cavity respectively.The output of driver A is connected with main magnet exciting coil, and the output of driver B is connected with secondary magnet exciting coil.
Driver A is as the master driver circuit, under the control of main control signal, the enable state control signal makes driver A produce the pumping signal of isolation and loss state, pumping signal produces magnetizing current by main magnet exciting coil, be applied on the ferrite switch, control respectively ferrite switch and be operated in isolation and two states of loss.Same driver B is as the backup drive circuit, under the standby control of control signal, the enable state control signal makes driver B produce the pumping signal of isolation and loss state, pumping signal produces magnetizing current by secondary magnet exciting coil, be applied on the ferrite switch, control respectively ferrite switch and be operated in isolation and two states of loss.Be subjected to the control of main control signal and standby control signal, synchronization driver A and driver B can not produce simultaneously pumping signal and be applied on the ferrite switch.
The present invention considers that ferrite switch has very high reliability, the inefficacy of ferrite microwave front end mainly is the inefficacy of drive circuit, thereby use the dual drive realization to the excitation of single ferrite switch, thereby solved that fallback circuit in the past brings because the equipment increase causes the too complicated problem of system, when reducing equipment volume and weight, satisfied spaceborne product to the requirement of equipment high reliability.
